COTTON-SACK STRAP.

Application filed March 12, 1925.

To alt whom t may concern:

Be it known that I, JAMES H. Coornn, a citizen of the United States,residing at Snyder, in the county of Kiowa and State of Oklahoma, haveinvented certain new and useful Improvements in Cotton-Sack Straps, ofwhich the following is a specification, reference being had to theaccompanying drawings.

This invention relates to the cotton sacks which pickers use and whichis provided with a heavy canvas strap by which the picker draws thecotton bag after him as he picks.

These cotton sacks are from twelve to fourteen feet in length andinasmuch as they are drawn over the ground, about onequarter of the sackis submitted to very heavy wear. Therefore, it becomes necessary atleast once a week to shift the strap so as to bring a new or unwornportion of the sack against the ground and put the` wear on a differentplace. It is the practice to sew this strap permanentlyV on the sewingmachine or by hand and it is considerable trouble to change the positionof the strap cach time it is necessary.

The object of my present invention is to provide means whereby the strapmay be readily attached to the sack or detached therefrom and wherebythe strap may be readily shifted from time to time as desired.

A further object is to provide a strap of this character which isadjustable to fit persons of different sizes and which is so constructedthat the clamp which holds the strap to the sack has no projectionswhich will be uncomfortable to the person.

A still further object is to provide a device of this character in whichthe strap is clamped to the sack by. metallic clamps through which lacespass, and to so construct the clamp that no strain will come upon thelaces themselves except the sti-'ain of holding the clamp in place.

Another object is to so form the clamp that the laces are held frombecoming accidentally released and tearing loose from the sack.

Still another object is to provide a clamp having perforations throughwhich the laces Serial No. 15,106.

is a section on the line 3-3 of portion of the sack, which sack is madeof' heavy canvas, and extending across the mouth portion of the sack isthe strap 10 also made of heavy canvas. The ends of this strap or bandare secured to the canvas by means of metallic clamps 11 formed of asingle thickness of sheet metal folded so as to extend downward oneachside of the wall of the bag, the fold being formed to provide a bead 12,this bead being disposed so as to project inward instead of beingcolui-dish tantly disposed or projecting entirely outward. The two metalleaves 13 of the clamp l1 are perforated at 14, these perforations beingso formed as to provide annular protuberanees or'prongs defining thehole and projecting inward or in the same direction. The annularprotuberance on the exterior leaf of the clamp will be forced inward,into the canvas of the sack. tapes in the form of shoe strings will bepreferably used for the purpose of binding this clamp to the sack, andone of these tapes is designated 15, these tapes being provided at theirends with the ferrules 16 like ordinary shoe strings.

Through the bead 12 is disposed one cross bar of an elliptical link 17and the ends of the band 10 are folded around this link and thenthreaded, thus giving a .fiexible and yet strong connection between theband and the clamping jaws, as they may be termed, of the clamp.Preferably the strap or band at one end is simply passed through thering 17 and is not sewed to the remainder of the band but is connectedto a sliding buckle or equivalent member 18 sothat the length of theband may be regulated. The tape is preferably threaded through theperforations 14 backward and forward first on one side and then on theother ofthe leaves 13 and of the material Iof the bag until the clamp istightly bound upon the bag and the 'ends of the tape will then' be tiedor left Tapes, cords, or'

flowing. liiasmuch as the jaws or leaves ll are brought tightly againstthe material of the bag and the annular protuberances or prongs at leaston one leaf are forced into the material of the bag, it is obvious thatthere will be practically no strain upon the laces or tapes l5 exceptthe strain due to holding the leaves or jaws closed shut upon the bag.

I have found by actual experience that this device may be readilyapplied and readily removed, that it is an easy matter, particularly ifthe tapes or strings are provided with pointed ferrules, as thefer-rules lr6, to force the ends of theI tape through the material ofthe bag and practically sew the clamp to the bag. It is, of course, evenmore easy to remove the tape and release the bag. By this means theposition of the two ends of the strap 10 may be readily changed upon thebag so that wear will come upon a new place and without the necessity ofsewing and picking out thel threads when it is desired to replace thepoint of engagement of the strap with the bag. Furthermore, all theprotuberances come upon the inside face of the bag so that only a smoothsurface is left to bear against the body of the wearer.

l. An attachment for engaging a strap with the top of a cotton pickingbag comprising a piece of metal folded to provide two parallel jaws, themetal at the junction of the jaws being formed to provide a bead, a linkengaged with said bead, the jaws being correspondingly perforated, and aHexible element adapted to be threaded through the perforations andthrough the material of the bag disposed between said jaws and back andforth across the jaws to thereby hold the clamp upon the baO.

2. Means for attaching the ends of supporting straps to the top of acotton pieking bag comprising a clamp formed of a folded piece of metalbetween which the top of the bag is to be inserted, the metal beingprovided at its fold with a bead and the two parallel pieces of metalhaving registering perforations at a plurality of points, a link engagedwith the bead, and a 'flexible element adapted to be threaded throughthe perforations and through the edge of the bag, the perforations onboth sides of the clamp heing struck up in the same direction.

A strap for cotton picking bags and clamps at the opposite ends of saidstrap, each clamp being formed to provide two opposed jaws engaging onoppositie faces et' the top margin of the bag, each of these jaws beingformed with a plurality of aligning perfor-ations, and the clamp at thejunetion of the jaws being formed to provide a bead, a flexibleconnection extending through said perforation and back and forth throughthe material of the bag and holding a jaws tightly pressed against theniaterial of the bag, and a link engaged with the bead and with whichthel strap is engaged.

et. A strap for cotton picking bags and clamps at the opposite ends ofsaid strap, each clamp being formed to provide two opposed jaws engagingon opposite faces of the bag at the top thereof, each of these jawsbeing formed with a plurality of aligning perforations and the clamp atthe junction of the jaws being formed to provide a bead, a fiexibleelement extending back and forth through said perforations and throughthe material of the bag and holding the jaws tightly pressed against thematerial of the bag, and a link engaged with the bead and with which thestrap is engaged, the perforations of the jaws being deined byprojecting walls, the walls of both jaws projecting in the samedirection toward the in-4 terior of the bag.

In testimony whereof hereunto aliix my signature.
